High-pressure shock-wave loading on stoichiometric mixtures of zinc oxide and ferric oxide powders produces partial conversion to a spinel structure zinc ferrite as shown by x-ray diffraction. The ferrite phase is characterized by a substantial saturation magnetization plus a high-field susceptibility. Since stoichiometric ZnFe/sub 2/O/sub 4/ is paramagnetic above 10 K, the magnetic behavior of the shock-synthesized spinel demonstrates that it is a zinc-deficient ferrite. X-ray diffraction data confirm that less zinc oxide is consumed than ferric oxide in producing the recovered spinel.
